Our Story

We opened BGB CrossFit in 2014 with a clear purpose: to provide the Fayette County community with a premier health and wellness experience grounded in expert coaching, proven methods, and genuine care. What brought us to CrossFit may have differed, but what united us was a shared belief in its power-its ability to transform lives through scalable, functional training for people of all ages and backgrounds. Our name, BGB, stands for Believe in the goal, Grind through the process, Become the goal-a reflection of our values and the mindset we instill in every member who walks through our doors. We believe lasting change starts with a clear vision, grows through consistent effort, and is realized through community and support. Our mission is to help every client achieve optimal health and exceed their personal goals. We go beyond workouts by continually expanding our knowledge and listening to the needs of our members. Over time, we’ve grown to offer not only CrossFit and small group training, but also functional nutrition coaching, movement screening, and massage therapy-delivering a truly holistic approach to wellness. These integrated services, combined with a results-driven, inclusive atmosphere, set BGB CrossFit apart as Fayette County’s leading fitness and wellness facility. Whether you’re just starting your journey or striving for new goals, we’re here to help you believe, grind, and become.

Kirsten Guilliams

Coach

CrossFit Level 1

CrossFit has been and continues to be one of the best decisions I have ever made. I first discovered CrossFit in 2010. A few years prior I had suffered an injury that ended my track and field aspirations early on in college. The community helped me feel like an athlete again both physically and mentally. Crossfit taught me what the body can overcome given the correct training. This led me to pursue a career helping others overcome their own physical restrictions. Since then my goal as a coach and manual therapist has been to help people move better and feel better both in the gym and in daily life.

Rod Sylvester

Coach

CrossFit Level 1

My CrossFit journey has done so much to promote my mental health and self esteem and I’m forever grateful for the very special friendships I’ve established through it. It’s an honor to coach people and help them on their individual fitness journeys. It’s such a rewarding process to see people come in everyday and get better, stronger and more confident in themselves. the coaches of BGB have done an amazing job not only with programming, but creating a safe/diverse space where people of all walks of life and fitness levels feel welcome and it’s an honor to now be a part of that team as well.

Ashley Harper

Coach

CrossFit Level 2

I’ve lived in Fayetteville since I was 4 years old. Graduated from Whitewater High in ’09 then went off to play collegiate softball at ABAC and Armstrong State University. When I moved back home in 2014, a good friend invited me to come workout with her at her CrossFit gym and I’ve been addicted ever since. In 2017, I decided to take the addiction a step further and get my L1 and have since acquired my level 2. I came to BGB for the fun and family-like feel. As soon as you walk in these doors, you are greeted with smiles and pushed, by each coach and athlete, to be a better version of yourself each and everyday. If you don’t find me at the gym, you can always find me with my family at a Braves game or softball field! Go Braves!

Holley Dallman

Coach

CrossFit Level 2

I started in gymnastics at a very young age and added weightlifting and track in her early teens. After being a “gym rat” my entire adult life, I was introduced to CrossFit in 2010. Shortly thereafter, I completed my first hero WOD, and was hooked. Over a decade later I continue to be impressed by the variety of movements Crossfit offers, building a comprehensive athlete like no other form of training. I also love seeing how Crossfit and its community transform people: “Crossfit is a community that accepts us for who we are, while at the same time encouraging us to better ourselves. The people around us believe we are capable of things we don’t see just yet, and that leads to victories we never thought possible.”

Karen Grahl

Coach

Fit Fast I started working out at CrossFit in January 2013. I had been faithful to exercise when I worked full time but found I wasn’t motivated after I retired. CrossFit was a whole new experience because I had never been much for working out in a group setting. CrossFit not only changed my workout habits but allowed me to lose the excess weight I had carried around for years and to be more functionally fit in my late 50’s and early 60’s. I don’t plan to stop participating in Crossfit anytime soon! In 2014, I started coaching the FitFast class made of people around my age. My goal for this class is to help and encourage anyone in their 50s and beyond to become functionally fit, gain muscle, expand their cardio resiliency and work on balance. The result you will see and feel is gaining back your health and fitness to be able to age gracefully but strong! The added bonus is the FitFast group camaraderie and the friends you will make within our community.
